Traumatic Tooth Injuries
A knocked-out or displaced tooth is one of the few genuine emergencies in dentistry, and what happens in the first sixty minutes has more influence on the outcome than anything done afterwards. If a permanent tooth has just been knocked out, call us now.

A permanent tooth has been knocked out — what to do right now
Pick the tooth up by the crown, never the root. If it is dirty, rinse it briefly in milk or saline — do not scrub it. If you can, place it gently back in the socket and hold it there. If you cannot, keep it in a container of milk, or in the injured person’s own saliva. Do not let it dry out. Then get to a dentist immediately.
The main types of dental injury
A chipped or fractured crown is the most common injury. If the fracture exposes the pulp, the tooth needs attention quickly; if it does not, the tooth may need only a restoration, but it should still be monitored because the blood supply can be damaged even when the tooth looks intact.
A luxated tooth has been pushed sideways, in or out of its socket without coming out. It usually needs to be repositioned and splinted, and monitored afterwards.
An avulsed tooth has come out completely. Time out of the socket is the single biggest factor in whether it can be saved, which is why the instructions above matter so much.
A root fracture is a break below the gum line. The outlook depends on where along the root the fracture sits — the closer to the tip, the better.
Injuries to children’s teeth are treated differently, because a root that is still developing has different healing potential and different treatment options from a fully formed adult tooth.
After a dental injury
What to do, and what to avoid
- Keep any tooth fragments — some can be reattached.
- Use a cold compress on the face to limit swelling.
- Eat soft food and avoid biting on the injured tooth.
- Seek attention even if the tooth looks undamaged; the blood supply can be injured without any visible sign.
- Attend the follow-up appointments — trauma is monitored over months, because a tooth can lose vitality well after the accident.
- If the injury involved a head impact, loss of consciousness or a wound needing stitches, seek medical attention first.
Common questions
Dental trauma FAQs
How long can a knocked-out tooth survive outside the mouth?
The sooner it is back in the socket the better; the cells on the root surface begin to die quickly once the tooth dries out. Storing the tooth in milk or in saliva keeps those cells viable for longer than water or a dry container. Treat it as an emergency and travel immediately.
Should I put a knocked-out tooth in water?
No. Plain water damages the cells on the root surface. Milk is the best readily available medium, and the injured person’s own saliva is a reasonable alternative. Never scrub the root or wrap the tooth in tissue.
My child knocked out a baby tooth — should I put it back?
No. A baby tooth should not be replanted, because doing so can damage the permanent tooth developing underneath. The child should still be seen so the area can be checked.
My tooth was knocked but looks fine. Do I still need to be seen?
Yes. A blow can damage the blood supply inside a tooth that appears completely normal, and the tooth may darken or become infected weeks or months later. Baseline testing and X-rays now make it far easier to detect a change early.
Dental injuries are time-critical
If a tooth has just been knocked out or displaced, call the practice immediately rather than waiting for an appointment.
